Some images do not display

hp

Hello,

After upgrading from 1.1.6 to 1.1.7, some images do not display: half of the album covers do not display, and then random images inside the albums do not display.

Any idea how to fix this?

Many thanks.

Have you reviewed the troubleshooting guide? http://www.zenphoto.org/2007/12/troubleshooting-zenphoto/

Honestly I didn't, but I did already check everything. For example, I already recursively set permissions to 777. Even though I shouldn't really have to because it's running phpsuexec.

The problem still persists. Any idea why upgrading caused this problem?

Thank you!

Common problems with images not displaying:

1. Image too big to be processed with the server memory availabl.
2. Mod_rewrite problems

You should check your error logs. Since some images are working #1 is the most likely problem.

Thanks.

But the images were originally displayed before the upgrade. And now they won't display? It's the same server and same server settings. Does that make sense?

Any idea what those errors are related to?

What is your PHP memory limit set to? Try increasing it and see if it makes a difference.

hp

I just set it to: memory_limit = 64M;

Make sure you restart apache (are you using apache?) after modifying your php.ini file. Are you still getting the same errors?

hp

it's on a shared hosting server so I can't restart apache

The first error is the only one of consequence. The second is a direct result of the error message display from the first error.

The error says that the GD handling routines did not like the the JPEG image that was passed to the function. In this case, the image is the one that is being processed for caching after resizing.

As to what the routines did not like, there is no information. But this might indicate a corrupted image.

I just reuploaded the image files but they are still not displaying. Do you have any other ideas? This problem started after I updated from 1.1.6 to 1.1.7.

Help is appreciated.

Did you check if they are published/visible?

hp

They are.

What happens is that the alt text (which appears to be the file name) is displayed instead of the thumbnail.

hp

I SOLVED IT. (After hours of testing)

I shrunk all my images to 80% and now they work. Anyone care to explain why?

acrylian

Yes, please see here: http://www.zenphoto.org/2008/08/troubleshooting-zenphoto/#11

I shrunk my images as well and it works perfectly and very quick. Thanks acrylian for the support.
